Your spreadsheet opened fine for me. There has been a delay in them opening for a while now. I don't know if it's Google or what.
Sorry about the fur shot, 'cause he was looking better on 1.5U. My advice about furshots is if you think it happened, feel for wetness and/or smell. Levemir smells awful, you can't mistake it. I know it's not advised to do this, but if it seems like nothing went in (there is wetness and smell), check BG in a couple hours and if it's gone up considerably like it did, consider giving a token dose, maybe half their current dose. That way they don't completely loose their shed.
Do you use 5/16th" needles or 1/2" needles?
If it makes you feel better, I was not with it this morning when I gave Gandalf his second split dose and I forgot to measure it with my micrometer, I just drew it to about .5U and gave it to him without realizing I hadn't measured it, until I was pushing the plunger in! So it was a bit over because he must have rebounded as he was upper 300s tonight. I knew it wouldn't hurt him to get what I shot, but I figured I would come home to either a low preshot or a high rebound preshot.
